No need to pass both and inode and a file as the former can be trivially
derived from the latter. But if I'm not misreading the patch, file is
entirely unused here anyway, so can't we just drop it and rename the
function to inode_needs_update_time?

I'd be tempted to just open code this in the two callers, but either
way works for me. If we keep the function please don't pass the
inode separately.
